php Laravel应用程序令牌不匹配异常错误

Question

我通过使用以下命令php artisan make：auth创建了登录和用户注册系统。 成功创建了所有必需的布局和刀片，包括数据库表，但是当我尝试注册用户时，出现以下错误。

TokenMismatchException

这是app.layout.blade.php的代码。

<!DOCTYPE html>

                                    </li>
                                </ul>
                            </li>
                        @endif
                    </ul>

        @yield('content')

    <!-- Scripts -->
    <script src="{{ asset('js/app.js') }}"></script>
    <script type="text/javascript">
      $.ajaxSetup({
        headers: {

        }
      });
  </script>
</body>
</html>

这是Register.blade.php代码的代码。

@extends('layouts.app')

@section('content')

这是我单击注册按钮时的输出。

Answer 1

尝试使用以下命令清除应用程序缓存：

php artisan cache:clear

Answer 2

如果您使用的是5.8，则应使用新的CSRF令牌代码。

@csrf

如果您碰巧使用ajax表单提交，则应使用以下标头：

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
